L3 IEC’s Modernized GPS Receiver Completes Successful Guided Flight Test

ANAHEIM, Calif. — L3 Interstate Electronics Corp. (L3 IEC) announced in July 25 release that its TruNav GPS is IEC’s first Military Code (M-Code) compatible GPS (Global Positioning System) receiver to guide a gun-launched spinning projectile to a target.

The guided flight test was conducted at Yuma Proving Grounds by the U.S. Army as part of a series consisting of both guided and unguided rounds. The unguided tests evaluated acquisition, navigation and upfinding performance, while the guided tests verified navigation and upfinding performance when using an M-Code receiver to navigate to a target. All testing was done in a benign environment with no Anti-jam or Anti-spoofing features.

“L3 is very pleased with the demonstrated performance of our GPS M-Code designs. We believe our family of industry-leading Assured Positioning, Navigation and Timing (A-PNT) solutions gives the warfighter an edge in battle,” said David Duggan, president of L3’s Precision Engagement Systems sector. “Our projectile GPS M-Code receiver is available in several form factors and is ready for integration into a wide variety of munitions requiring next-generation GPS performance to counter current and future threats.”

The L3 IEC TruNav projectile GPS receiver module is a 46mm round card low-power system that receives and processes GPS signals for gun-launched, air-dropped and rocket-propelled precision-guided munitions. The module uses a baseline M-Code architecture developed by L3 under the Air Force’s Military GPS User Equipment (MGUE) program. The MGUE baseline provides affordable precision in a GPS-degraded and -denied environment, and maintains accuracy while exposed to Blue Force Electronic Attack.
